In July 1925, when Alfred Don Munday [1890–1950] and Phyllis Munday [1894–1990] made an expedition into the Cariboo Range, he noted that two parties of climbers had preceded them: Edward Willet Dorland Holway [1853–1923] and Dr. Andrew James Gilmour [1871–1941] in 1916; and Allen Carpé [1894–1932] Premier Rangeand Rollin Thomas Chamberlin [1881–1948] in 1924 [1].

The latter party made two major climbs, the first ascents of Mt. Titan (11,850 ft.) and Mt. Challenger (10,900 ft.). They also climbed three minor mountains: Gunboat (10,000 ft.); a shoulder of Mt. Titan which they called Bivouac Peak (10,150 ft.) and a triple summit (10,250 ft.), which Mr. Munday refers to as Holway’s Peak, he having made the first ascent of its northerly summit. (The elevation and other names are Mr. Carpé’s.) [2]

Sterling Brown Hendricks [1902–1981] and Andrew John Kauffman [1920–2002] prefaced a 1950 article with:

The seldom visited Cariboos are one of the most northerly and extensive mountain chains of interior British Columbia. They are also known — perhaps officially — as the McLennan Range, while the higher peaks are called the Premier Group. In this article the names of the peaks originally given by Allen Carpé and Don Munday are used. The region’s center lies some 15 miles southeast of Tête Jaune, a station on the Prince Rupert line of the Canadian National Railroad, in the triangle of high peaks formed by Mount Titan (Sir Wilfrid Laurier, ca. 11,750 ft.), Mount David Thompson (Sir John Thompson, ca. 11,250 ft.) and Mount Kiwa (Sir John Abbott, ca. 11,200 ft.). The mountains are high and heavily glaciated, but not especially difficult for the alpinist [3].

Many place names in the region were changed by the Premier Range proclimation in 1927.
